Detection of Edges in Spectral Data II. Nonlinear Enhancement
Anne Gelb,Eitan Tadmor +1 more
TL;DR: Gelb and Tadmor as discussed by the authors proposed a general framework for recovering edges in piecewise smooth functions with finitely many jump discontinuities, where $[f](x): = f(x+)-f(x-)

Journal ArticleDOI
A method to reduce the Gibbs ringing artifact in MRI scans while keeping tissue boundary integrity
Rick Archibald,Anne Gelb +1 more
TL;DR: The Gegenbauer reconstruction method has been shown to effectively eliminate the effects of Gibbs ringing in other applications and is presented in this paper as a solution to the problem of reconstruction of magnetic resonance imaging data with Gibbs ringing.
Journal ArticleDOI
Polynomial Fitting for Edge Detection in Irregularly Sampled Signals and Images
TL;DR: A new edge detection method that is effective on multivariate irregular data in any domain based on a local polynomial annihilation technique and can be characterized by its convergence to zero for any value away from discontinuities is proposed.
Journal ArticleDOI
Robust reprojection methods for the resolution of the Gibbs phenomenon
Anne Gelb,Jared Tanner +1 more
TL;DR: An additional requirement on the reprojection basis is proposed which ameliorates the limitations of the Gegenbauer reconstruction and yields a reliable exponentially accurate resolution of the Gibbs phenomenon up to the discontinuities.
